REAL-TIME SOLAR EVACUATED TUBE SIMULATOR
The simulator comprises python script which models an evacuated tube collector in the computer. Physically, it consists of a laptop (for running the python script) linked to a control signal generator which regulates the power, via a solid state relay, into cartridge heaters with built-in Thermocouples that can mimic the heat output from an evacuated tube. The simulator can operate in real-time, meaning a typical day can be simulated in the laboratory, by taking a weather data file and generating a control signal to input the exact amount of heat for that time of day.
Using the simulator, Solar Polar have been able to optimise the thermodynamic performance diffusion-absorption cooling system before field trials.
